But it cost me around RM3k to fix, not 6K at Sapura Auto.I was driving to Singapore and sometime around Melaka, same thing that happened to you, happened to me.Yellow Engine Temp high warning showed up asking you to slow down. So i turn off the A/C, slow down but after a minute or so, the red one showed up saying Engine Overheated. Ask you to stop and call BMW.So i stopped the car. Turned it off, then got out. Locked the car. Unlocked the car, came back in. Started the car, and hey, no more message!So i drove all the way to singapore fine. And i drove all the way BACK from singapore fine too. Very spirited driving too. HeheSo i didnt think anything into it. 3 months later on another trip down to Singapore, it popped out somewhere around Sepang exit. Same thing, it went away after a restart.But this time it came back at Seremban, Melaka, Tangkak and a few more times. I knew it was getting more serious but after Kluang exit, it started raining and i didnt have an issue anymore? I think maybe the water cooled down the engine? So i made it all the way to Singapore. Back from Singapore, it happened once and never again, but then again, it rained all the way back.So when back in KL, i continued driving for another month or so before sending in the car for service and it seems nothing happens in the city?Correct me if im wrong but shouldnt the engine be HOTTER when stuck in the traffic jam in the city as opposed to flying on the highway when theres so much air going through the radiator?In the end, according to Sapura auto the water pump was faulty. The part cost RM3k and fixed the problem for me. According to them, the water pump is an electric water pump and when you're on the highway (maintaining constant rpm), the water pump might fail or not go on momentarily causing the engine to rise in temperature abit and get that warning. But the engine ISNT really overheated (oil temp 100c above). its actually just a little bit over acceptable and henceforth when i turn off the car and back on immediatly (and the water pump starts working), its okay again, for awhile.I hope this was helpful and maybe not everyone needs to spend rm6k.The funny thing till today for me was tht this would happen on highways and not in the city stuck in a jam at noon with the scorching mid day sun. I would think that it would be hotter that way.</blockquote>
